d0b69cf119 Remove NEON vmull, vmlal, and vmlsl intrinsics, replacing them with multiply,
add, and subtract operations with zero-extended or sign-extended vectors.
Update tests.  Add auto-upgrade support for the old intrinsics.

188da252ab Tweak to ignoring reserved regs. The allocator was occasionally still looking
at them since they'd end up in the register weights list. Tell it to stop
doing that.

97511ceffa Recommit with changes. Comment out palignr for the
moment, as there's a testcase that uses it and expects it
to be subject to optimizations; we won't be doing that.
Some adjustments based on feedback from Bill.

29c353b9c3 Using target specific nodes for shuffle nodes makes the mask
check more strict, breaking some cases not checked in the
testsuite, but also exposes some foldings not done before,
as this example:

  movaps  (%rdi), %xmm0
  movaps  (%rax), %xmm1
  movaps  %xmm0, %xmm2
  movss %xmm1, %xmm2
  shufps  $36, %xmm2, %xmm0

now is generated as:

  movaps  (%rdi), %xmm0
  movaps  %xmm0, %xmm1
  movlps  (%rax), %xmm1
  shufps  $36, %xmm1, %xmm0

d4c454317a Make tool_output_file's raw_ostream instance a member variable instead

formatted_tool_output_file.

91abace4ef add a gross hack to work around a problem that Argiris reported
on llvmdev: SRoA is introducing MMX datatypes like <1 x i64>,
which then cause random problems because the X86 backend is
producing mmx stuff without inserting proper emms calls.

In the short term, force off MMX datatypes.  In the long term,
the X86 backend should not select generic vector types to MMX
registers.  This is being worked on, but won't be done in time
for 2.8.  rdar://8380055
